Each webview has several variables that are passed in by the chatbot when creating the webview. You can access the variables using double braces, like this:
const accessToken = '{{webview_access_token}}';
const appId = '{{facebook_app_id}}';
const nextPassage = '{{next_passage}}';Need more data?
You can also access data you’ve stored for a user using the context_data endpoint. See Get context data.
Variables
| Name | Code | Description |
|---|---|---|
| Facebook App ID | {{facebook_app_id}} | The chatbot’s Facebook App ID. |
| Next Passage | {{next_passage}} | The passage the chatbot should go to after the webview is closed by the start_passage endpoint. See Start passage. |
| Webview Access Token | {{webview_access_token}} | The access token prevents users from reloading out-of-date webviews from earlier in the conversation. It must be added to the query string of every webview endpoint call using the parameter accessToken. |
